' ROLL-SCREEN FOB WINDOWS.

Specification of Letters Patent.

Patented Nov. 13, 1917.

Application filed October 10, 1916. Serial No. 124,795.

To all whom it may concern:

Be it known that 1, DAVID EDWARDS, a subject of the King of Sweden, and a resident ofthe city of New York, borough of Brooklyn, in the county of Kings and State of New York have invented a new and Improved Roll-creen for Windows, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved roll screen arranged for convenient attachment to windows without requiring alteration thereof, and adapted to properly screen the window from top to bottom and from side to side to prevent insects from passing into the room and to allow convenient rolling u of the screen for opening or closing the window sashes whenever it is desired to do so. Another object is to combine with. the roll screen supports for a window shade and curtain pole.

In order to accomplish the desired result, use is made of brackets, adapted to be attached to the window-.frame at the sides thereof, a spring actuated roller journaled in the said brackets, a screen winding and unwinding on the said roller and provided with spaced battens, one of which is at the bottom of the screen, guideways attached to the sides of the window frame and engaged by the ends of the said battens, manually controlled catches mounted in the ends of the said bottom batten, and keepers in the lower ends of the said guideways and adapted to be engaged by the said catches to lock the screen in lowermost position and with the bottom batten in contact with the sill of the window.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a front elevation of the roll screen for windows as applied and with part broken out;

Fig. 2 is a cross section of the same on the line 22 of Fig. 1;

Fig. 3 is an enlarged cross section of the casing and one of its supporting brackets attached to the window frame, parts of the bracket being broken out;

Fig. 4 is an enlarged sectional plan view of a portion of the roll screen and one of its guideways, the section being on the line 44 of Fig. 1;

Fig. 5 is an enlarged sectional plan view of the lowermost batten, its guideway, and the locking device in one end thereof, the section being on the line 5-5 of Fig. 1;

Fig. 6 is a cross section of a modified form of the roll'screen as applied; and

Fig. 7 is an enlarged cross section of the bottom batten.

The roll screen in its general construction Fig. 4, and the ends of the battens 15 extend into guideways 16 attached to the sides of the window frame or casing 12. Each of the guideways 16 is preferably made tubular with a guide slot 17 at the inner side for the passage of the corresponding ends of the battens 15, and the terminals of the battens 15 are preferably provided with friction rollers 18 bearing against the inner face of the inner side of a guideway.16 (see Fig. 4) to insure an easy up and down movement of the 'screen 14. One of the battens 15 is arranged at the bottom of the screen 14 and in each end of this batten 15 is mounted a catch 20 adapted to slide lengthwise of the batten. Each spring'catch 20 is pro, vided with a handle 21 adapted to be taken hold of by the operator, and the spring catch is pressed on by a spring 22 to normally project the outer beveled end 28 beyond the corresponding end of the batten. This outer beveled end 23 is adapted to engage a spring keeper 24 secured to the corresponding guideway 16 at the inside thereof (see Fig. 1) and this spring keeper 24 is so arranged that when the catch 23 engages the keeper then the bottom batten 15 is in contact with the sill of the window frame. In order to insure a very firm contact between this bottom batten 15 and the sill, use is preferably .made of a strip of rubber or other similar material 25, inserted between the two members of the bottom batten at the under side thereof, as plainly indicated in Fig. 7

When the screen 14 is in extended position it reaches from the top of the window frame to the sill thereof, and as it extends into the guideways 16 attached to thesides of the casing, it is evident that this entire window is covered to properly exclude in sects and the like.

A guide roller 30 is journaled in the brackets 10 a distance below the roller 13 and farther inward so as to guide the screen 14 to the guideways 16, as will be readily understood by reference to Figs. 2 and 6. When it is desired not to use the screen, the Operator presses the handles 21 of the'spring catches 20 inward to disengage the outer ends 23 thereof from the keepers 24, and then the operator allows the screen to slide upward and wind up on its spring-actuated roller 13. VV-hen the screen is rolled up convenient access is bad to the window sashes to permit of conveniently opening and. closing the same, and when it is desired to again use the screen it is only necessary to pull it to lowermost position so that the spring catches 20 reengage the keepers 24 and thus lock the screen in lowermost position agamst the tension of the usual spring in the roller 13.

In order to protect the screen when wound up on its roller 13, use is made of a casing 40, preferably of sheet metal, and open at the ba ck, as plainly indicated in Figs. 2 and 3. The bottom 41 of this casing 40 is adapted to fit into a guideway 42 formed transversely on the inner face of each bracket 10, and the top 43 of the casing 40 fits into similar guideways 44 formed on the inner faces of the brackets 10. The guideways 44 are inclined upwardly and rearwardly so that when the top 43 is engaged with the guideways 44 and the bottom 41 is engaged with the guideways 42 then the easing is held securely in place on the brackets but can be readily removed therefrom whenever it is desired to do so. The brackets 10 may be attachedto the top of the window frame, as plainly shown in Fig. 1, or to the inner faces of thesides immediately below the top, as plainly shown in Fig. 6.

In the construction disclosed in Figs. 1, 2 and 3, the brackets 10 are provided with bearings 50 for supporting a curtain pole 51, and the brackets are also provided with depending bearings 52 for supporting the roller 53 of the shade 54 so that special brackets for the shade roller and the curtain pole are not necessary.

When using the brackets below the top at the inner faces of the sides of the frame, then the supports 50 for the curtain pole are dispensed with and the brackets are provided with bearings 52 for the roller 53 of the window shade 54, as will be readily understood by reference to Fig. 6.

The roll screen shown and described is very simple and durable in construction and composed of comparatively few parts which can be readily placed in position on the window frame, as above described.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent 1.
